[APG Public List] [APG Members] Exciting New Dimension for DNAResearch

One problem on some online genealogical DNA databases is that many 
unverified pedigrees were submitted, and that has to have an impact. The DNA 
hits would then take you to possibly an individual who in turn has wrongly 
identified common ancestors.

If a person has submitted their DNA but attached it to the the wrong 
individuals, how could that be identified and corrected.  I think you'd 
still have to then go and verify that person's ancestral research before 
drawing any conclusions?

Or am misinterpreting the risk here?

  I understand what you were saying now.  Wow, I wonder what the odds are of 
finding matches.  Do they publish any numbers?  Number of entries in their 
database you can match against, average number of matches?

  I'm also wondering if there are any other DNA testing companies that 
affordably test X and autosomal chromosomes to the degree necessary to find 
relationships the way 23andme does?  I see Family Tree DNA offers those 
tests at reasonable prices.  Are those sufficient?  Of course, then they 
would also have to facilitate the matching process.

  It would be interesting to either have a master database or service that 
DNA testing companies participate with to find relationships across DNA

    Males inherit a single X chromosome from their mother and they get a Y

mother and the other from their father. Normally, taken alone, I'd not be 
able to tell which was which--but this match has to be with my dad's X 
because my mother's wouldn't have matched his from his mother because our 
relationship is provable through my dad and his mother. His mother had TWO X 
chromosome as all females do--but she would only pass one along to her son 
or daughter and the father would contribute the other -- an X or a Y 
depending upon the sex of the child. (There are some rare males who inherit 
an extra X and are XXY but that is very rare and, don't laugh, has been 
associated with a proclivity for being a mass murderer--for real, I'm not 
making this up).

      what a great story Joan!  I'm going to have to try 23andme now.  I'm 
just curious about one little thing, you wrote, "what we share is a 
mind-boggling match on the X chromosome--through his mother (his only X) and 
my X inherited from my father."  What did you mean by "his only X?"  I 
assume you mean his mother's only X?
